-- modMask lets you specify which modkey you want to use. The default is
-- mod1Mask ("left alt"). You may also consider using mod3Mask ("right

-- Anything non-zero here will leave a gap of that many pixels on the
-- given edge, on the that screen. A useful gap at top of screen for a
-- menu bar (e.g. 15)
--
-- An example, to set a top gap on monitor 1, and a gap on the bottom of
-- monitor 2, you'd use a list of geometries like so:
--
-- > defaultGaps = [(18,0,0,0),(0,18,0,0)] -- 2 gaps on 2 monitors

-- numlock handling:
--
-- The mask for the numlock key. You may need to change this on some systems.

-- $ xmodmap | grep Num
-- mod2 Num_Lock (0x4d)
